Description
Technical field
The present invention relates to centrifugal pump, be specifically related to the axial rolling bearing of a kind of centrifugal pump.
Background technology
At present, the axial rolling bearing of low-specific-speed narrow runner type centrifugal pump (power≤800,
It includes sliding bearing and rolling bearing etc.) commonly used rolling bearing band disc thin oil profit certainly
Sliding mode: all employings sliding bearing thin oil forced feed lubrication that power exceedes；Higher at power,
When this boundary value, due to impeller outlet and the vane inlet of low-flow high-lift type centrifugal pump
The most narrow, the opening value difference value of stator and impeller is smaller, looks for the runner of pump rotating shaft and housing
Centering difficulty is big.The deviation of centering, the rotor forces being easily generated pump rotating shaft increases.For improving
Improve rotor forces, the axial force bearing the deviation of centering and produce, a kind of self-lubricating and pressure
Lubrication combines and adapts to the arid axial rolling bearing lacking water area pumping unit will be as grinding
The emphasis sent out.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency, and provide a kind of greasy property more may be used
Lean on, can improve to improve and bear the double of the centrifugal pump of axial force produced by pumping unit centering deviation
Lubricated type axial rolling bearing.
The purpose of the present invention realizes by following technical solution: the dual lubrication formula thrust of centrifugal pump
Bearing arrangement, including bearing body, bearing cap, sliding bearing, rolling bearing, disc,
Described bearing cap is provided with oil-feed port, the jet of close rolling bearing, this oil-feed port and oil spout
Form oil supply gallery between Kou, the inwall of described bearing body is provided with oil level dividing plate to form profit
Lubricating oil pond, is provided with oil return opening on described bearing body and in the outside of this oil level dividing plate.
After using the present invention, owing to have employed by oil-feed port, jet, oil supply gallery, rolling
Bearing, be provided with the lubricating oil bath of oil level dividing plate, oil return opening formed forced feed lubrication mode, by getting rid of
The thin oil self-lubricating mode that oil ring, sliding bearing and rolling bearing are formed, the most also can use wind
Fan forcing functions mode, the greasy property making this bearing arrangement is relatively reliable, and can be effectively improved
Axial rolling bearing bear pumping unit centering offset issue produce pump rotating shaft rotor forces,
Axial force, reduces the maintenance cost of pumping unit, extends the service life of pumping unit, and it is special
It is not applicable to the pumping unit in arid few water area.Using effect of the present invention and economic benefit are obvious,
There is significant technological progress.
Accompanying drawing explanation
With embodiment, the present invention is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the dual lubrication formula axial rolling bearing of centrifugal pump of the present invention.
Fig. 2 is the A-A view of Fig. 1.
Detailed description of the invention
Understanding with reference to Fig. 1, Fig. 2, it is powerful that the present invention is applied to low-specific-speed narrow runner type
The dual lubrication formula axial rolling bearing of centrifugal pump, including bearing body 1, bearing cap 4, sliding axle
Hold 3 (and sliding bearing pressure rings 18), rolling bearing 7, disc 2 (for two pieces, one
In this sliding bearing 3, another part is at this rolling bearing 7 side), on described bearing cap 4
It is provided with oil-feed port 5, the jet 6 of close rolling bearing 7, this oil-feed port 5 and jet 6
Between formed oil supply gallery 16, the inwall (both sides) of described bearing body 1 is provided with oil level
Dividing plate 11 is to form lubricating oil bath 12, on described bearing body 1 and at this oil level dividing plate 11
Outside be provided with oil return opening 10.
Wherein, described bearing body 1, bearing cap 4 are respectively arranged with fin 9；Oil supply gallery
16 inside bearing cap 4, and rolling bearing is implemented oil spout；The inwall of bearing body 1 and oil
The inner side of position dividing plate 11 forms the lubricating oil bath 12 of certain altitude, and interior storage has lubricating oil for by force
System and self-lubricating use.In order to this bearing arrangement being carried out cooling better, more effective, dissipating
Heat, described bearing body 1, bearing cap 4 be peripherally equipped with fan guard 14, at this centrifugal pump
Equipped with fan 8 in rotating shaft 17 and at bearing body 1, this fan guard 14 is provided with into
Air port 13 (between the exit of this fan guard 14, fin 9, there is air-out passage 15).
Referring to the drawings, the present invention work of high-power low-specific-speed narrow runner type centrifugal pump it is applied to
Principle is: lubricating oil is first entered into and through jet dextrad rolling by a left side by the oil-feed port of bearing cap
Dynamic bearing fuel feeding, returns to be provided with the lubricating oil bath of oil level dividing plate after the rolling bearing of biserial
In, make the oil level of this lubricating oil bath remain at normal position, unnecessary lubricating oil then passes through
Oil level dividing plate overflows and is returned to small-sized oil-servicing facilities by oil return opening, thus formed one overall
The miniature running system of forced feed lubrication.In this bearing arrangement, sliding bearing and rolling bearing depend on
The old disc structure that maintain thin oil self-lubricating, in pumping unit running, disc with
The relative motion friction of the rotating shaft of centrifugal pump, makes disc follow rotating shaft rotation direction to rotate, profit
Lubricating oil in lubricating oil pond is brought into inside two bearings along with the rotation of disc, further through two bearings
Return to lubricating oil bath with the gap of rotating shaft, thus form self lubricating system.This bearing arrangement cold
But system is then made up of, in operation fin, fan and the fan guard of the proper alignment outside it
The heat that bearing arrangement produces is realized by this cooling system: air is entered by the air inlet of fan guard
Enter, make air accelerate by the rotation rotarily driving fan of rotating shaft, the effect of fan guard make
Air after acceleration is discharged along the air-out passage between fin, thus formed one complete
The cooling system of outer logical forced air cooling mode.
